Delayed-Action Catalysts for Polyether-Based Soft Polyurethane Foams: An In-depth Guide

Introduction Polyether-based soft polyurethane (PU) foams are widely utilized in various applications, including furniture, bedding, automotive interiors, and packaging. The production of these foams typically involves a complex chemical reaction between isocyanates and polyols, which is catalyzed to control the formation of urethane bonds and the release of carbon dioxide (CO2). Delayed-action catalysts play a…
